Abstract

The invention relates to a cementitious composition that can effectively reduce the adsorption of water, which comprises a) at least one polymer that is the polymerization product of oneor more ethylenically unsaturated monomers, in the form of their polymer dispersions and water-redispersible polymer powders; and b) at least one alkyl and/ or alkenyl substituted dicarboxylic acids or anhydrides.
